Description:
Author(s): Lucile Savary, Kate A. Ross, Bruce D. Gaulin, Jacob P. C. Ruff, and Leon Balents Here we establish the systematic existence of a U (1) degeneracy of all symmetry-allowed Hamiltonians quadratic in the spins on the pyrochlore lattice, at the mean-field level. By extracting the Hamiltonian of Er 2 Ti 2 O 7 from inelastic neutron scattering measurements, we then show that the U (1)-degener... [Phys. Rev. Lett. 109, 167201] Published Mon Oct 15, 2012
